CAR-LOCK.

SPECIFICATION forming part of Letters Patent Ne. 650,561, dated May 29, 1900.

Application filed March 11, 1899- To all whom it may concern:

Be it known that I, THOMAS B. KIRBY, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oar-Locks, of which the following is a specification.

This invention relates to car-locks, and is in the nature of an improvement upon the carlock set forth in Letters Patent No. 605,860, granted to me June 21, 1898. l

The present invention has for its object to provide a car-look which shall be free from certain objections which are found to be attendant upon the particular form of construction set forth in my said prior Letters Patent under certain conditions and which shall be less expensive to construct, easier to manipulate, and less liable to injury by breakage.

To these ends my present invention consists in certain novel features, which I will now proceed to describe and will then particularly point out in the claims.

In the accompanying drawings, Figure 1 is an elevation of a structure embodying myin- Vention in one form. Fig. 2 is a sectional view of the same, taken on the line 2 2 of Fig. 1. Fig. 3 is an enlarged detail view of the device in front elevation; Fig. 4, a side view of the same; and Fig. 5, a longitudinal sectional view, partly in elevation.

In the said drawings, indicates the wall of the car, and 11 the car-doors, which are hinged thereto at 12. These doors are locked in the usual manner by locking-bars 13, passing through guides 14 on one of the doors, adapted to engage with keepers 15 on the carbody, being operated by means of a link 16, centrallypivoted on said car-door, and having the locking-bars pivoted to its free ends.

17 indicates the locking-lever, which also. serves as a locking-hasp, being slotted, as shown at 18, to receive a loop or staple 19, located on one of the locking-bars 13 and adapted to pass through the slot 18 and receive a locking-pin on the outer side thereof. The staple l9 and slot 18 are arranged transversely to the vertical, as set forthin my prior Letters Patent hereinbefore specified,

the construction in other respects being that usual in looks of this class and being shown for purposes of illustration as it may obviously be modified without affecting my invention. Y

Serial No. 7081772. (N0 model.)

20 indicates the locking-pin,which is mount- 7 thereof, while theslot 23 is curved, as shown,

the under portion of the bodyof the pin being correspondingly curved,'for the reason hereinafter set forth. It will be seen that the locking-pin is thus not only capable of sliding longitudinall y relatively to the lever or hasp, but

that it also has a free pivotal movement relatively thereto, so thatits lower end may be free to swing outward in the manner indicated in dotted lines in Fig. 4. The lower portion of the locking-pin 20 is reduced to a size which adapts it to pass through the slot or opening in the staple 19, and the lower extremity of said locking-pin is provided with'an aperture 24 to receive the securing means, such as a seal or locking device in the nature of a padlock or the like. In the construction shown, the lever or hasp 17 is provided with a lug 25, lying in a vertical plane at right angles to the body of the lever or hasp and having an aperture 26, which is adapted to register with the aperture 24 in the lower end of the locking-pin 20 when this latter is in the position shown in full lines in Figs. 3 and 4. When this construction is employed, the sealing or locking device is passed through both of the apertures 24 and 26; but when the lug is dispensed with said device is passed through the aperture 24 only.

The locking-pin 20 is desirably provided with a projection 27 on its outer face,by means of which it may be readily lifted when desired. I

The car-lock set forth in my prior Letters Patent hereinbefore referred to While a desirable and efficient look under ordinary circumstances has been found inpractice to be liable to become clogged in winter-time by the gathering of ice and snow in the guide or keeper and its slots, thereby hindering the ready movement of the locking-pin. It has also been found that when by accident or inadvertence the lever is moved into locking position with the locking-pin in a lowered position or when said pin has dropped into a lowered position during such movement of the lever the attempt to force the staple through the slot in the lever will bring it into.contact with the locking-pin and will tend to damage or break the parts. All of these difficulties are obviated by the construction which I have hereinbefore set forth, as it will be seen that there are no contracted guideways or narrow slots which are liable to become filled with snow or ice or other obstructive matter, and since the locking-pin is free not only to slide longitudinally of the lever, but is also pivotally connected therewith, so as to be free to swing outward at its lower end, it will be observed that when the lever is moved to the locking position shown and the staple projects through the slot th ereof said staple coming into contact with the lowerend of the locking-pin, in case this latter is allowed to hang free and has not been held up by hand during this operation, will'swing said lockingpin outward in the manner indicated in dotted lines in Fig. 4, and there will therefore be no danger of any breakage of or damage to the parts of the lock. 'lhelocking-pin may obviouslybe eitherheld up byhand during the engagement of the lever with the staple and then allowed to drop through the staple-aperture into the position shown in full lines in Figs. 3 and 4, or it may be allowed to swing freely outward during the engagement of the lever and staple and may be then moved up by hand into the position shown in Fig. 5 and then allowed to slide downward through the aperture in the staple into locking position. The curvature of the slot 23 and of the under or inner face of the body of the lockingpin adjacent thereto provides sufficient clearance to permit the longitudinal movement of the locking-pin relatively to the guide-pin 22 when the locking-pin is in the extreme angular position relatively to the lever shown in dotted lines in Fig. 4:, permitting the clearance by the upper inner edge of the lockingpin of the adjacent outer face of the lever 17. It will also be observed that the construction set forth is of a simpler character and involving less expense to manufacture than that set forth in my said prior Letters Patent.

I do not wish to be understood as limiting myself strictly to the precise details of con-v struction hereinbefore described and shown in the accompanying drawings, as it is obvious that they may be varied without departing from the principle of my invention.

I claim-- I. In a car-lock of the character described, the combination, with a locking-bar having a loop or staple, and a hinged slotted operating-lever, of a locking-pin mounted to slide longitudinally relatively to said operating-lever and havingits lower end free to swing o'utward therefrom, substantially as described.

2. Ina car-lock of the character described, the combination, with a locking-bar having a loop or staple, and a hinged slotted operating-lever, of a locking-pin mounted in bear-- ings to move longitudinally relatively to said bar, onenf said members being provided with per portion to receive said guide-pin and having its lower portion adapted to pass through the loop or 'staple and free to swing outwardly from the operating-lever when disengaged therefrom, substantially as described.

4. In a car-lock of the character described, the combination, with a locking-bar having a loop or staple, and a hinged slotted operating-lever having a transverse guide-pin, of a locking-pin having a longitudinal slot in its upper portion to receive said guide-pin and having the under or rear portion of its body adjacent thereto curved,substantially as described.

5. In acar-lock of the character described, the combination, with a locking-bar having a loop or staple, and a hinged slotted operating-lever provided with a transverse guidevpin, of a locking-pin having its upper portion longitudinally curved and correspondingly slotted to receive said guide-pin whereby it is free to swing outwardly from the lever when unlocked, substantially as described.

6. In a car-lock of the character described, the combination, with a locking-bar having a loop or staple, of a hinged slotted operating lever having a longitudinal groove to form a guidewa-y and a transverse guide-pin, and a locking-pin adapted to slide in said guideway, having a longitudinally-slotted upper portion to receive the guide-pin and having its lower portion adapted to pass through the loop or staple said locking-pin being free to swing outwardly when disengaged from the loop or staple, substantially as described.

7. In a car-lock of the character described, the combination, with a locking-bar having a loop or staple, and a hinged slotted operating-lever, of a locking-pin mounted on said lever and longitudinally movable relatively thereto, the lower portion of said locking-pin being adapted to pass through the loop or sta ple and beingrprovided with an aperture to receive a looking or sealing device, and the lever being provided with a projecting lug having an aperture adapted to register with the apertureof the locking-pin, substantially as described.
